Hi! Since kernel 6.1.22 starting a resume from hibernate by hitting a key on the keyboard fails. However, if the PC was switched off and on again (or reset), the resume is OK. The APU is a Ryzen 5600G.
Bisecting between 6.1.21/22 turned up this:

drm/amdgpu: skip ASIC reset for APUs when go to S4 commit b589626674de94d977e81c99bf7905872b991197 upstream. For GC IP v11.0.4/11, PSP TMR need to be reserved for ASIC mode2 reset. But for S4, when psp suspend, it will destroy the TMR that fails the ASIC reset.[...]
Reverting the commit solves the problem. Thanks.
Please try 6.1.23 and report back, because from the thread https://lore.kernel.org/all/20230330160740.1dbff94b@schienar/ it sounds a lot like "drm/amdgpu: allow more APUs to do mode2 reset when go to S4" might be fixing this, which went into 6.1.23.
Yes, 6.1.23 seems OK so far.
The patch " drm/amdgpu: allow more APUs to do mode2 reset when go to S4" is to fix this hibernate regression issue.
Sorry to have troubled you.
No problem, please don't take it personally. It wasn't a big deal and I was just a bit grumpy yesterday.
Thanks for the info and have a good day!
